Hair analysis is perceived as an effective method for detecting drug and alcohol consumption. Hair records a prolonged history of substance utilization by encapsulating biomarkers in the strands' structure. When taken near the scalp, hair can offer a detection period for alcohol and other substances of up to three months. Hair is straightforward to gather, relatively tough to tamper with, and simple to transport.
A 1.5-inch segment composed of about 200 hairs (roughly equivalent to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is the optimal specimen for both screening and confirmation tests. For EtG, additional tests, and/or screens beyond 10 panels, 150mg of the hair sample is advised. It's best to measure the sample on a jeweler's scale. Should scalp hair not be available, an equal quantity of body hair may be utilized. "Head hair" specifically pertains to scalp hair, while "body hair" includes other types like facial and axillary hair.
Process Overview
The four essential stages in laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample into a lab's system. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry not provided by an electronic chain of custody system.
Screening consists of a quick preliminary check for the presence of abusive substances. While considered a cost-efficient approach to exclude drug usage in most samples, any positive findings during Screening require further confirmation to be courtroom admissible. Samples that are suspected to be positive in Screening require an additional confirmation process.
For samples presumed positive in Screening, further hair is extracted from the initial sample and set for Extraction. At this stage, drugs are derived from hair at a lower concentration than in other methodologies (e.g., urine or oral fluid), which explains why hair drug screening is the most complex methodology to conduct.
Confirmation of any screening positive result is conducted using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if required. The entire lab process involving Accessioning through Confirmation undergoes evaluation under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
